To all whom it may concern.-

Be it known that I, CARL RICHARD MARTIN, inechanician, asubject of theKing of Saxony, residing at Dresden, Kingdom of Saxony, Ger man Empire,have invented certain new and useful Improvements in or Relating toCigarette-Machines,'of which the following is a specification.

Since fiat cigarettes have been introduced that is to say, cigarettes ofelliptical or approximately elliptical cross-sectionthe demand for themhas been always on the increase.

The present invention has for its object to provide a machine forproducing such cigarette which shall be simple and inexpensive; and itconsists in certain novel details of construction and combination ofparts, all as will now be described, and pointed out particu larly inthe appended claims.

As the rod is constantly moving, the press is mounted on a reciprocatingpart of the machine, (the knife-slide,) which carries also the knife, sothat the press, like the knife, advances to meet the rod, catches it,and compresses it.

In the accompanying drawings, Figure 1 is a side elevation, and Fig. 2 aplan view, of the end of the frame-cheeksA of a cigarettemachine withthe knife-slide B. Fig. 3 is a front view of the knife-slide and itsappurtenances, the cheeks of the frame being in section. Figs. 4 and 5are views similar to Fig. 1 with certain parts omitted for the sake ofclearness and other parts added, and Fig. 6 is a vertical transversesection of the press on a larger scale than that to which the otherfigures are drawn. In Figs. 1, 3, and 4 the upper die e of the press Eis raised. In Fig. 5, which otherwise agrees with the first fourfigures,the upper die is, on the contrary, shown lowered, and the sameis the case in Fig. 6.

C, Fig. 2, is the end part of the shapingtube for forming thecigarette-rod.

c is the endless band coming out from the tube 0 and guided downward bythe pulley d. The cigarette-rod runs in the direction of the arrow inFig. 2.

E is the press hereinbefore referred to, 6 being the upper and e thelower die thereof. The cigarette-rod S, Fig. 3, formed in the tubeO,with the aid of the endless band 0, together with the paper covering,is, as hitherto, cylindrical. (See the circular cross-section s in Fig.3.)

The knife-slide Bis arranged at one side on the knife-shaft b by meansof arms I), attached tov the slide. The knife-shaft reciprocates instandards B, secured to the cheeks A of the main frame. The bottom plateof the knife-slide at the side opposite to that which is arranged asaforesaid is supported by the roller 1), carried in bearings on the mainframe. (See Fig. 3.) The reciprocating motion of the knife-slide isimparted to it by the lever B which is actuated by a cam. (Not shown inthe drawings.) The curved knife-disk M, which is fixed to the shaft bbetween the arms 17, is rotated by a chainpulley m, (shown by dottedlines in Figs. 1 and 2,) or may be rotated by any other gear.

Directly behind the knife-disk M is placed the press E, as shown,through which the cigarette-rod S, guided by a fixed eye 1, Figs. 1 and2, must pass in order to pass through a tube 2 after having passed bythe knife. The press E comprises a fixed lower die 6 and thevertically-reciprocating upper die 6'. The cross-section of the channelof the press (see Fig. 6) is formed by two arcs of a circle, so that thedies 6 e compress the cylindrical rod S, Fig. 3, in such a way that anelliptical section 8, Figs. 2 and 6, results. The upper die 6 is guidedin its vertical movement by bolts 3, secured in the lower die 6, and toits opposite sides are pivoted links 4, Figs. 2 and 3, which connect theupper die with the lever arms 5. These latter are mounted on a pin 6,which is supported in the lower die e and carries the lever-arm 7. Thefree end of the arm 7 carries a laterallyprojecting pin 11 and issuspended by the spring 8, which is secured to the arm F, fixed and inthe same direction.

on the frame. On the inner side of the arm F there is an inclinedcam-bar f, which acts as a cam on the pin 11 of the-lever '7. A plate 9is carried on the upper ends of the bolts 3, and below it is a spring10, which is stronger than the spring 8 and just so long that with theparts in the position shown in Figs. 1, 3, and t it forms an elasticabutment for the upper die whenever the latter is lifted by the spring 8and lover 7, as shown in the said figures, but when the parts are in theposition shown in Fig. 5 has no influence whatever on the upper die. Aslong, therefore, as the cam-barf does not act the upper die remains inthe upper or raised position in which it is shown in Fig. t and the pin11 on the lever 7 reciprocates along the line .r of the same figure.

From the position in which the slide 1 is shown in Fig. i it movesba-ekthat is to say, in adirection opposite to that in which thecigarette-rod advances. Thelatter passes through the eye 1 into thepress E, and then the return movement of the slide 13 commences with thevelocity of the cigarette-rod Next the pin 11 on the lever 7 runsagainst the cam-barf, by which it is pressed down, and then the press isclosed, the several parts of the mechanism taking the position inwhichthey are shown in Fig. 5. Just before that position is reached thecutting edge of the knife M approaches the flattened rod and thecnttingtakes place, the closed press holding the rod so that a clean cutis effected. Meanwhile the pin 11 011 the lever 7 has passed the loweredge of the cambarf. Then the spring 8 begins to act and lifts the upperdie c till it touches the spring 10 and the pin 11 on the lever 7 againis in the line 47) 00. As soon as in the return of the slide the pin 11comes against the back of the cam-bar f the upper die is raised higherup, the spring 10 being compressed till the upper edge of the cam-bar freleases the pin, when the spring 10 again brings about the originalposition of the parts, as shown in Fig. t. The arrangement of springspartly working against each other has the object of permitting the pin11 during its advance to pass under the cam and to pass over the barf inthe return stroke. This is necessary, as the cam is shorter than thepath of the slide, for the press is not to be closed at the beginning ofthe described operation and is to be opened immediately after the end ofthe operation in order to receive the rod, which has meanwhile advanced.The same object can of course be achieved by other means.

I elain1 1. In a cigarette-machine, the combination with thelongitudinally-moving knife for severing the rod, of alongitudinally-reciprocating press operatively connected with the knifefor pressing the cigarette into elliptical form, before being severedfrom the cigarette-rod; substantially as described.

2. In a cigarette-makingmachine, the combination with the main frame A,of a reciprocating knife-slide, a reciprocating press operativelyconnected with the knife-slide and furnished with channeled dies forpressing the cigarette into elliptical form, a lever operativelyconnected with one of the press-dies, and a cam-bar f secured to astationary part of the machine; substantially as set forth.

3. In a cigarette-making machine, the combination with the main frame A,of a reciprocating knife-slide, a reciprocating press operativelyconnected with the knife-slide and furnished with channeled dies forpressing the cigarette into elliptical form, one placed above another,guides 23 for the upper die carried by the lower one, a spring 10supported above the upper die by the guides 3, a lever 7 operativelyconnected with the upper press-die, an inclined eam-barfand its supportF, secured to a stationary part of the machine, and a spring 8connecting the end of the lever 7 with the support F; substantially asset forth.

4:. In a cigarette-making machine, the combination with a reciprocatingknife-slide, of a reciprocating press operatively connected with theknife-slide and having press-dies so grooved on their opposing faces, asto form a channel of approximately elliptical eross-section between themand means for operating one of the dies.

In testimony whereof I have hereto set my hand in the presence of thetwo subscribing witnesses.
